Hi, I'm 15 wks + 6. The last couple days I been feeling weird things in my lower abdomen. If I lay or sit down and am very still I can feel a weird fluttering/bubbling feeling occasionally. It's slight and It's also really fast (only lasting a second or so) but it's getting more noticeable. Does this sound like movement? It's my first so I was expecting a bit longer wait but I have health anxiety so it's an understatement to say I'm really in tune with any weird feelings in my body
